Serial No. 338,285.

This invention relates to machines for and methods of operating on heels and is herein exemplified in its application to forming grooves or slots in the breasts of wood heels adjacent and parallel to the corners formed by the breasts and the sides of the heels to receive and retain the margins of coverings extending around the rear and sides of the heels.-

1n United States Letters Patent No. 1,7 04,- 204, granted on March 5, 1929, on application of `William H. Nutt, there is described a Cuban heel having two side cover retaining grooves or slots arranged adjacent to and parallel with the corners or edges formed by the breast and the sides of the heel.

An object of the present invention 1s to provide a machine constructed and arranged for forming in the breasts of Cuban heels cover retaining grooves such as those illustrated in Figs. 6 to 10, inclusive, of the abovementioned patent.

`W ith the above object in view, one feature of the present invention consists in the provision of means for supporting a heel placed thereon, grooving or slotting means extending beyond the supporting means, and a gage constructed and arranged to engage the side 'of the heel to facilitate the guiding of the heel over the supporting means as the heel is moved past the grooving means to form a groove or slot in the breast of the heel.

Another feature of the invention consists in the provision of a machine for forming grooves such as those above-mentioned, which machine is so organized as to insure against the splitting of the heel. To this end and in accordance with the illustrated embodiment of the invent-ion, a table which supports the heel for operation thereon by the grooving means and the gage which engages the side portion of the heel may be tilted relatively to the grooving means to provide for cutting grooves at varying angles in the heel breast.

A still further feature, of the invention consists in the provision of a machine for forming grooves such as above described at various distances from the breast corners of the heels. The illustrated machine is provided with means for varying the distance between the gage and the grooving means in order to change the position of the grooves to be cut in the breasts of the heels relatively to the breast corners of the heels.

1n accordance with a further feature of the invention, the machine is provided with means, illustrated as a turret for carrying gages having dierent shapes, the turret being constructed and arranged to facilitate the selecting and positioning of the gages relatively to the grooving means and the heel supporting means.

In its method aspect, as herein exemplified, the invention is recognized in forming grooves in the breasts of Cuban heels near one of the breast corners of the heel and following substantially the contours of the breast corners, which consists in positioning a heel relatively to a grooving means by utilizing as positioning elements the breast of the heel and a portion of the side of the heel adjacent to that breast corner of the heel near which the groove is to be formed, and moving thepheel past the grooving means to form a groove in the heel breast near said corner while utilizing the heel breast and said portion of the side of the heel as guiding elements to determine the path of the heel.

rl`he machine illustrated as embodying the invention, and with the aid of which the invention may be advantageously practiced, will now be described with reference to the drawings.

Fig. 1 is a front elevational view of the i1- lustrated machine, parts being broken away to show the interior construction thereo;

Fig. 2 is a plan view of the machine;

F ig. 3 is a perspective view of a heel the breast of which has been grooved by the ma-2 chine illustrated in Figs. 1 and 2;

Fig. 4 shows a construction for forming grooves in the breasts of heels at different angles of inclination to the breast surfaces of heels; and

Fig. 5 is a detail view of the machine illustrated in Figs. 1 and 2 showing the heel supporting table and the grooving means.

The illustrated machine is constructed and arranged to form heel cover receiving grooves or slats A (Fig. 3) in the breast B of a Cuban heel C substantially parallel and adjacent to their respective breast corners D formed by the junction of 'the breast B and the sides of the heel, one of which is indicated bythe reference ycharacter E.

The machine includes a standard 12 (Fig. 1) having a central upwardly extending portion 14 upon which is mounted a table 16 for supporting a heel C laced breast down thereon, and two lateral y extending portions 18 for supporting relatively to the table 16 circular saws 20 extending above or beyond the table (Fig. 1) and gages 22 which are arranged to engage the sides of the heels and to serve as guides when a heel is moved over the table 16 past the saws 20.

In order that the rooves A may be successively formed ad]acent to each of the breast corners or edges D while the heel is moved in one general direction along the table 16, the illustrated machine includes a pair of groove forming units (Fig. 2) cooperatively positioned out of alinement with one another on opposite sides of the table 16. Since the units are substantial duplicates of one another except insofar as certain of their parts are reversed, it will be necessary to describe but one of the units.

The table 16 has a fiat upper surface 24 constructed and arranged to be engaged by opposite breast corners D of heels in order that each of the heels may be fixed against rotation about its vertical axis when placed breast downwardly on the table, thus insuring that the saw will enter the heel breast at a predetermined an le. The table is provided with recesses 26 ig. 5) having dovetailed portions 28 along their sides, which recesses extend partly across the width of the table `and are constructed to receive slides 30 (Figs. 1 and 5) each slide having its inner end portion cut away to form an opening 34(Fig. 1) for the reception of one of the saws 20.

Mounted upon each of the laterally extending portions 18 of the standard 12 is a block 36 (Fig. 1) having an opening 38 extending therethrough. Passing through and securedl `within the opening 38 is a bronze bearing 40 which serves rotatably to support a shaft 42 carrying at its outer end a pulley 44 adapted to be connected with a source of power. The opening 38 in the block 36 includes an oil well 46 for purposes of lubrication.

The shaft 42 is provided with an end section 48 of reduced diameter which has a threaded recess 50 in its end for the reception 0f a screw 52' (Fig. 1) to force the saw 20 tightly against the end of the shaft 32 so that the saw will rotate therewith.

In order to support the ages 22 the block 36 is provided with upwardly extending portions 54 and 56 (Fig. 1) which serve-to support a turret 57 having a downwardly extending portion 58 the lower face of' which cess 62 in t e upwardly is arranged to seat upon the top face of the upwardly extending portion 54 of the block 36. The upwardly extending portion 56 of the block 36 has a dowel'retaining sleeve 59 threaded thereon to limit upward movement gjaddowel in 60 which is slidable in a reextending portion 56 and 1s urged upward y against the sleeve 59 by a spring 64.

T e turret 57 includes a plurality of arms 6.8 (Figs. 1 and 2) and gage attaching portlons (Fig. 2) upon which portions gages 22 are mounted. Each arm 68 is provided w1t h a tapered dowel pin receiving recess 72 (Fig. 1) arranged to receive the dowel pin 60 for circumferentially locating the turret selectively to position any one of the gages 22 in heel guiding relation to the table 16 and saw 20.

The turret 57 may be rotated about a stub shaft 74, fixed to the upwardly yextending portion 54 of the block 36 by a pin 76 and passing vertically through the turret 57 which is provided with an opening 78 for receiving the stub shaft 74.

In order to clamp the turret 57 in operative position (Fig. 1) the stub shaft 74 is provided with a cam 90 which is pivotally mounted upon a bifurcated portion 86 (Fig. 2) of the stub shaft 74 through a pin 88. For conveniently operating the cam 90 a handle 92. is formed integral with the cam, which handle when rotated in a counterclockwise direction,

as shown by dotted lines in Fig. 2, will release the cam 90 so as to allow the turret to be raised to the position indicated in dotted lines in Fig. 1. The cam 90 may be constructed and arranged for direct engagement vwith the top surface of the turret itself, but it has been found convenient to attach a washer 89 of relatively soft material upon the upper surface of the turret to afford better clamping action between the turret 57 and the cam 90.

In order to assist in selectively positioning the gages 22 adjacent to the supporting table 16, the machine is provided with a spring 8O which encircles the upwardly extending portion 54 of the block 36 and the downwardly extending portion 58 of the turret 57, the ends of the spring 80 being in contact with faces 82 and 84 of the turret and the block, respectively, thereby tending normally to urge the turret 57 away from the block `36 to raise the turret so that the dowel pin receiving recess 72 is raised from the dowel pin 60 upon release of the cam 90, thus leavingV the turret 57 in a position for conveniently rotating it upon the stub shaft 74.

Each of the gages 22 is of substantial height and has an arcuate heel engaging face 100 (Fig. 2) which is spaced from the saw .20 and retreats upwardly from said saw when in operative position (Fig. 1) adjacent to the surface of the table.

sides of heels are not always uniform. It is- In the manufacture of wooden heels it is necessary to abrade or spool the lower side portions of heels near the breast corners to reduce the width of the lower portions of the heel breasts. Since the spooling is usually carried out by hand, the curvatures of the desirable that the groove A should follow its respective breast corner throughout the length of the groove and for this reason it is necessary that the face 100 of the gage 22 should engage the heel as close to the breast corner of the heel as practicable. Since the arcuate faces 100, above described, retreat upwardly away from the heel, as shown in Fig. 1, each gage 22 contacts with the side of the heel only along a line close to a breast corner thereof, thus insuring the forming of a groove A which is of equal distance from the breast corners throughout its length. Contact with portions of the side of the heel which are remote from the breastcorner and the curvature of which may be different from the curvature of the breast corner itself is thus avoided.

The arcuate outside faces 100 of the various gages 22 on the turret 57 are of different contours or curvatures to accommodate diferent types and sizes of heels and the operator may conveniently select the gage having a curvature corresponding to the curvature of the heel which is to be grooved.

When it is desired to change gages, the handle 92 is swung to the left (Fig. 1), thereby allowing the spring 8O to raise the turret 57 The turret 57 is then rotated upon the stub shaft 74 until the selected gage is in its proper position over the table 16. The gage is next lowered in its proper circumferential position adjacent to the surface 24 of the table by swingng the handle 92 to the right, the dowel pin thus engaging the dowel pin receiving slot 72 in the arm 68 corresponding to the selected gage.

In order to vary the distances between the breast corners D of different heels and the groovesA, each saw 20 may be moved within its corresponding opening 34 in the direction of the width of the table 16 thereby changing the distance between the arcuate face 100 ofl the gage member 22 in position upon the table and the saw 20. A split collar 102 is mounted upon the shaft 42 and the shaft is provided with an axially extending recess 104 arranged to receive a set screw 106 carried by the pulley 44, the recess 104 being wide to lprovide against movement of the lengthwise thereof. a

As previously stated, in order toavoid any tendency toward splitting the heel, such as might otherwise result from locating the marginal grooves A throughout their depth ,Shaft near the breast corners of the heel, it is often i desirable to form the grooves in the breasts of the heels at varying angles transversely of the heel relatively to the breast surfaces of the heels and substantially following the contours of the heel breast edges. To this end, as illustrated in Fig. 4, the machine may be provided with a table106, which table 106is split along its center line into two sections 108 each of which, together with a' gage 110 which rests upon it, may be tilted at various angles to the saw 20 so that during various grooving operations the saw may enter the heel at varying angles.l

In order to allow the table 106 and the gage 110 to be conveniently tilted relatively t0 the saw 20, each gage 110 is provided with a recessed portion 112 and each section of the table 106 is provided with a s lot 1 14 for the reception' of the reduced portion 48 of the shaft 42 as relative tilting takes place between the shaft and the table and gage. The degree of tilting of each section of the table 106 may be changed by any convenient means such as a segment of a gear 116 which engages a worm 118 rotated through a worm shaft 120 to tilt each of the table sections 106 and the gages 22 at any desired angle relatively to its corresponding saw 20.

In carrying out the grooving operation, a heel C (Fig. 2) is moved along the surface 24 of the table 16 with its breast face down upon form a groove A. The illustratedhecl breast B is concaved so that the heel engages the table only along its breast cornersD. The heel breast, however, may be only slightly concaved or flat, in which case the heel will engage the table over a substantial portion of the breast of the heel.

By providing a pair of heel grooving units having gagesdisnosed at opposite sides of a common table (Figs. 1 and 2), a groove may be formed in the breast of a heel close to one breast corner thereof and following the contour of that breast corner, as above indicated, and by continuing the movement of the heel in the same general direction along the surface of the table in engagement with the other gage and past the other grooving means, a groove may be formed in the breast of the heel adjacent to the other breast corner and following the contour of that breast corner.
